This research guide...

The purpose of this research guide is to provide an introduction to the basic resources and sources for the study of the writings and teachings of the Fathers of the Church and the Patristic Age. As such, it lists the major introductions and handbooks to the patristic literature, the monumental sets containing the texts of the Fathers in the original language, the major series of translations of the Fathers into English, as well as other resources, dictionaries and tools that illuminate the writings, doctrinal teachings, theological disputes, heresies and controversies of the first eight centuries of the Christian church.

Good starting place

Early Christianity drew on a variety of sources - Jewish ideas, Greek philosophy, Greek and Latin vocabulary - in an attempt to explain complex theological formulations.
